Efficacy and safety of self-retaining double-needle barb suture in transabdominal path robot-assisted laparoscopic partial nephrectomy for T1 renal cancer.

Objectives: This study evaluated the safety and efficacy of self-retaining barbed double-layer sutures (SRBDS) used for wound sutures in stage T1 renal cancer undergoing peritoneal robot-assisted laparoscopic partial renal resection.

Methods: A total of 50 patients undergoing robot-assisted laparoscopic partial nephrectomy (RAPN) for localized renal tumors (< 7 cm) in Zhejiang Provincial People's Hospital from January 2021 to January 2022 were selected. The experimental-group and the control-group randomly included 25 patients, respectively. SRBDS was intended to be used for kidney wound repair in the experimental group, and single-needle Vicryl was applied in the control group.

Results: Patients in both the experimental group and the control group completed RAPN without conversion to open surgery. The operative time (80.20 ± 18.39 min) and warm ischemia time (11.76 ± 1.16 min) of the experimental group were both reduced compared to the control group (86.00 ± 15.94 min, 14.56 ± 1.04 min). The increased changes in blood creativity at one week and three months postoperatively in the experimental group were significantly lower than those in the control group, and the decreased changes in GFR level at three months postoperatively in the experimental group were significantly lower than that in the control group (5.21 ± 2.14 vs 7.81 ± 2.28, P < 0.05).

Conclusion: For localized T1 renal carcinoma, SRBDS is a safe and efficient endoscopic suture technique, which may be considered as an alternative to other suturing techniques, tissue sealants, and glues for RAPN in the future.
